ABSTRACT:
The invention relates to a method and a device for distance measuring between two stations (A1, B1) connected by a communication channel. The method is based on a command structure, wherein the satellite (A1, B1), by means of which a distance is to be determined, sends a range request (3) via an inter-satellite communication channel to the other satellite (A1or B1), which thereupon acknowledges this range request (3) with an answer (4). The distance is determined from the corresponding measurement of the cycle time. The range request (3) and the corresponding answer (4) are transmitted in a multiplexed communication channel.
